What is a transrectal ultrasound?
An ultrasound is a way to get images of within the body without the use of x-rays, and instead sound waves are utilised. These sound waves that are used bounce back from the internal structures which gives images.
A transrectal ultrasound is where the probe is inserted internally via the rectum. This is sometimes used instead of an abdominal ulstrasound as when the probe is inserted internally it is able to show better images of the prostate and surrounding structures.
This scan will give your doctor a more accurate idea of the volume (size) of your prostate over a normal abdominal ultrasound
Asking for your consent
The clinical team will ask you if you are happy for the scan to go ahead (verbal consent). If you do not wish to have this scan or are undecided, please tell the clinical team. It is your decision and you can change your mind at any time. Please remember that you can ask the clinical team any questions you have at any time.
What happens during the scan?
A healthcare assistant will collect you from the waiting room to take you through to your scan where they will confirm your details. You may be asked to change into a gown.
They will confirm your details with you such as your name some details with you, such as your name and date of birth.
The radiologist will come into the room after reviewing any previous imaging and may ask about your history or any symptoms
You will then be asked to lie on the ultrasound table. For this scan you will be lying on your left side with your knees pulled up.
The radiologist will use a small ultrasound probe. The probe is covered with a probe cover for hygiene reasons. This is gently inserted into the rectum. Once inserted the radiologist will gently move the probe to get a clear picture of the rectum and surrounding areas.
Does the scan hurt?
Having a transrectal ultrasound should not hurt. You are likely to feel a little pressure but no discomfort
How long will the scan take?
The scan itself should only take a few minutes but you’re advised to have at least 30 minutes set aside for your appointment.
